BUTTON.

1 Application filed. July 29,

T 0 all whom it may concern.

Be it known that I, ERNST KLEINMANN, a citizen of the German Republic,residing at Berlin, Germany, and State of Prussia, have invented certainnew and useful Improvements in Buttons, of which the following isaspecification.

This invention relates to buttons with an outside coating or covering ofany suitable kind of material such as cloth or the like which completelyinclosesthe whole top portion of the button. Durable buttons of thiskind could hitherto only be made with the aid of machinery. Therefore itwas not possible for dressmakers, housewives, etc., to make such buttonsthemselves. 1 In distinction from those known typeset buttons thepresent invention enables the button with its covering to be made byanybody without the aid of tools. To render this possible the button iscomposed of two spring'parts adapted to engage with one another andbetween which the material forming the covering is clasped or clipped.

Some constructional forms of the invention are shown in the drawing inwhich Fig. 1 is a section of a finished button,

Fig. 2 is a plan view of the bottom or base portion of the button,

Fig. 3 is a section of a button with a spring clipping plate, v

Fig. 4 is a plan view of the base portion of a button provided withserrations of a special kind,

Fig. 5 is a modification of Fig. 3 and Fig. 6 is a modification of Fig.5.

As shown in Figs. 1 and 2 the upper half of the button is covered withcloth 0. The base portion 7) of the button is made of two parts and hasan annular shoulder b and an upper indented portion which, when it ispushed into the upper half, has its outer edge turned downward so as toturn the cloth back over a ledge at the bottom of the upper part a asshown in Fig. 1. The ring of teeth on the base portion firmly holds thecloth 0 clipped in between the base 5 and the upper part a.

In the modification shown in Fig. 3 the base portion 5 is provided witha special spring plate (I which is pressed into the top Specification ofLetters Patent. Patentg1IAug, 22,

oortion a and then causes the cloth coverillustrated. This arrangementensures that cloth coverings of very different thicknesses 'will alwaysbe seized by at leastsome of the teeth the longest teeth taking effectif the cloth is very thin and shortest if the stuff is very thick. Inthe l long teeth would be bent back so far that their points would notafterwards enter the cloth.

In the modification shown in Fig. 5 the atter case the base portion 5equipped with a spring plate 0? with a ring of downwardly extend inoflaring teeth which are not uniform but of diil'erent lengths for thereason mentioned above. v

A special type of the kind of button shown in Fig. 5 is illustrated inFig. 6 in which the base portion Z) is formed with steps b, so that ithas a conical shape and may be pressed more easily into the top portion.The steps 2), also enable the teeth 0Z (Z, of the spring plate (Z tomove out of the way. "i

In order to avoid the danger of the thread passed through the transversehole of the base portion 5, and by which the button is sewed on, frombeing damaged by the button beingrotated. the lower part of the baseportion, i. e. the part that receives the thread, may be adapted torotate freely relatively to the part oi? the base portion that grips thecloth covering 0 of the upper portion a of the button. This may beaccomplished'by adapting the thread-receiving part .7), of Fig. 1 toloosely embrace the lower flange-shaped part of the serrated gripping orclipping member 7), or by adapting the spring plate d of Figs. 3, 4C, 5,6 to revolve freely on the rivet or neck I), by which it is attached tothe'lower part of the base portion.
